I think we'd want the entire game. You can add multiple view options if the player wants to see the screen only.

After reading the Wikipedia article on "Handheld electronic game", what are the chances of emulation of the Bandai LCD Solarpower games which used 2 stacked LCD screens (https://en.wikipedia.org/wiki/Bandai_LCD_Solarpower), the Tomytronic 3D games which also used 2 LCD screens with a window to let in external light to simulate the 3D effect (https://en.wikipedia.org/wiki/Tomytronic_3D) or the Tuttuki Banko with it's finger control (https://en.wikipedia.org/wiki/Tuttuki_Bako)? I'd be willing to donate towards getting something like these into the hands of a dumper.

Tomytronic 3D: interesting smile MCU is UCOM-75, not known how to dump yet, and not emulated yet.
Bandai LCD Solarpower: find out what MCU it uses.
pokey thing: still being sold by Bandai/made profit on?

I have one of the bandai solar power LCD games. it does not have two stacked LCDs I didn't think. It has two "screens" for the game, but it appears to do this by simply lighting up different segments.

The game I have is "nazono pyramid". Of course it's a glop top so there's no way to know what CPU it has or dump it nondestructively unfortunately.

It depends on the game, the ones he is talking about are called 'Double Panel', like the LCD Zaxxon or Terror House: (Pretty sure the clam-shell flip games are just single LCD)
http://www.handheldmuseum.com/Bandai/TerrorHouse.htm
http://www.handheldmuseum.com/Bandai/ZaxxonLCD.htm

There's at least 5 different Double Panel games (each one linked to on the top of either of those pages above). Pretty sure they all have the 'glop' chip... Can those be uncovered easily enough to see the die? I think I have a beater version of Zaxxon I'd be willing to sacrifice, if I still have it... (Too much crap, I keep loosing track of what I have and what I've sold over the years... Must get an inventory system in place. smile )

There's also ones like this:
http://www.handheldmuseum.com/Bandai/PenguinLand.htm
with two LCD screens for head-to-head play

And then these crazy things:
http://www.handheldmuseum.com/Bandai/Gundam.htm
with a second hinged LCD panel, so sometimes you playing panel #1, sometimes panel #2, and sometimes both panels stacked on top of each other...

The Tomy 3D games I think just use a single LCD with only half being visible in each eye. So you could emulate half the screen for 2D playback, and then just support Oculus Rift at somepoint... smile smile

[Edit] Yeah, patent for Tomy 3D games here:
https://www.google.com/patents/US4561723
Shows the single LCD. So implementation of 2D emulation might be simple enough if we can figure out the chip.

And, Kevin, games on their way to you tomorrow:
Bandai Dokodemo Dorayaki Doraemon
Bandai Machine Man
CGL Earth Invaders
CGL Super Kong
Entex Select-a-Game with Space Invaders and Football carts
Gakken Dig Dug
Mego Mini-Vid Sea Battle (LCD)
Vtech Invaders

I've de-globbed several dies using heat, acid and/or a chemical called Decap.

On another front, Mattel Armor Battle has a Hitachi HD38133 28-pin DIP. Anyone have info on it? The closest I could find is HD38702/HMCS42, but the pinout is different. The PCB has jumpers for TANK/SUB, so Sub Chase probably also uses it.

rik: cool, sounds awesome that some games are on the way. I'm working hard on HDMI NES but need a break. hehe. I have 15-17 games here backed up that need VFD vectoring. I dumped most of the CPUs. hopefully this week I'll get that done.

I was involved in a bad car wreck a bit over a week ago on friday, but I'm fine. my car sure wasn't though so I had to go through the hassle of dealing with all that. I got most of it done now, however. Making a left and someone ran the red light and demolished my car and that drove me into a 3rd car. Got another car saturday and took the rental back tonight.

sean: not heard of that part yet. Did you check out bitsavers and poke thru the hitachi databooks on there?

ucom75 we don't yet know the trick to dumping them; they're used in a few vfd games, and in the Epson PX-8 'Geneva' as a slave/battery control MCU.

Interesting note on Entex Pac-Man 2... I have two of these here, both the same chip number (A23), and in demo mode, they both do the _exact_ same thing every time. I can turn them both on at the same time, and the pac-man and ghosts will follow the same pattern, every time. There's two different patterns- one is triggered by starting demo without the VFD test, and the other is triggered by doing the VFD test.

MESS does the same thing (two patterns, triggered by with or without the VFD test), but the patterns are completely different than what I get on the actual units...

Normal game play seems to work fine, just curious why the demo patterns would be different...

One or more registers might be getting initialized differently in the emulation than in the actual games, or the game might read an address to seed the random # generator and that address returns a different value in the actual games. In the same vein, the hack to make arcade Ms Pac ROMs run on a Pac Man PCB makes the normal patterns not work because the random # generator uses the ROM contents.
